A client who is primigravida at term comes to the prenatal clinic and tells the practical nurse (PN) that she is having contractions every 5 minutes. The PN monitors the client for one hour using an external fetal monitor, and determines that the client's contractions are 7 to 15 minutes apart, lasting 20 to 30 seconds, with mild intensity by palpation. Which action should the PN take?

Tell the client to go directly to the hospital for admission to labor and delivery for active labor.

Send the client home and tell her to drink at least 1,000 mL of fluid each day to flush her bladder.

Send the client home and instruct her to call the clinic when her contractions occur 5 minutes apart for one hour.

Direct the client to check into the hospital within the next hour for evaluation of possible urinary tract infection.
